Identification of RNase T as a high-copy suppressor of the UV sensitivity associated with single-strand DNA exonuclease deficiency in Escherichia coli.

There are three known single-strand DNA-specific exonucleases in Escherichia coli: RecJ, exonuclease I (ExoI), and exonuclease VII (ExoVII). E. coli that are deficient in all three exonucleases are abnormally sensitive to UV irradiation, most likely because of their inability to repair lesions that...
